Get out your ISN! You will be able to understand the basic ideas of probability including outcomes, events, and sample spaces. Today’s Objectives:

2
Warm Up Tape this into your Warm Up Section and use the deck to answer.

3
WWK & TOC Choose a colored pencil and ruler—draw a horizontal line underneath… the last TOC entry ( ) the last WWK entry ( Standard Deviation )

4
TOC WWK If you number your WWK… start numbering at 1 again!

5

Big Picture

7
Unit 3 We are now moving to Unit 3 which is Probability. The definition of Probability is the chance that something will happen—how likely it is that some event will happen.

8
Probability Recall that randomness— randomly assigning subjects to treatments in experiments, or randomness in sampling in observational studies— is a key component of statistics. Probability gives us a way to measure randomness.
